The session examines the role of the metaphysical and physical in art and animation and how this relates to natural spaces. Soviet Russian film director and theorist Sergei Eisenstein saw animation as possessing an ability called “plasmaticity”, the capacity for a being to assume any conceivable form dynamically. He saw each being as “primordial protoplasm, not yet possessing a ‘stable’ form, but capable of assuming any form” (Eisenstein 1989, 21). He was enamoured by the capacity of animation to transform and be liberated, of being able to escape from a fixed and static identity—to embody a "rejection of the once-­‐and-­‐forever allotted form" in which we are held (Eisenstein 1989, 21). Czech Surrealist animator Jan Švankmajer uses a metaphysical approach based on a belief in animism to art and animation. He believes that objects possess a conscious life or spirit, he says ‘Objects conceal within themselves the events they’ve witnessed. I don’t actually animate objects. I coerce their inner life out of them.’ (Švankmajer in Imre 2009, 214) In this animistic world there are no boundaries or rules, no physical or conceptual restrictions; anything is possible, with inanimate objects and places able to become animate and transact in a conscious relationship with humans and each other. This session invites artists, animators and theorists to discuss their conceptions and approaches to using visuals to promote and provoke transformation.

Det finns en mätbar entitet i all levande materia, nämligen förhållandet mellan ett atomslags lätta och tunga isotop. Denna entitet divideras med en definierad referens och ett värde erhålls som brukar anges i promille ( ). Värdet är ett mått på isotopfraktionering. Genom att studera ekologi, taxonomi, kretslopp, isotopeffekter, dokumenterad data och metabola effekter kan man skissera över vad isotopfraktionen betyder. Migrationsbeteende, trofinätverk, dieter, miljö- och klimatdata kan rekonstrueras i tid och rum. Vid rekonstruktioner av gången tid har de museala samlingarna en nyckelposition. I litteraturöversikten tas teori, praktik och forskning upp för att påvisa metodens faror och användningsområden.

This study Contested Lands: Land disputes in semi-arid parts of northern Tanzania. Case Studies of the Loliondo and Sale Division in the Ngorongoro District concentrates on describing the specific land disputes which took place in the 1990s in the Loliondo and Sale Divisions of the Ngorongoro District in northern Tanzania. The study shows the territorial and historical transformation of territories and property and their relation to the land disputes of the 1990s'. It was assumed that land disputes have been firstly linked to changing spatiality due to the zoning policies of the State territoriality and, secondly, they can be related to the State control of property where the ownership of land property has been redefined through statutory laws. In the analysis of the land disputes issues such as use of territoriality, boundary construction and property claims, in geographical space, are highlighted. Generally, from the 1980s onwards, increases in human population within both Divisions have put pressure on land/resources. This has led to the increased control of land/resource, to the construction of boundaries and finally to formalized land rights on village lands of the Loliondo Division. The land disputes have thus been linked to the use of legal power and to the re-creation of the boundary (informal or formal) either by the Maasai or the Sonjo on the Loliondo and Sale village lands. In Loliondo Division land disputes have been resource-based and related to multiple allocations of land or game resource concessions. Land disputes became clearly political and legal struggles with an ecological reference.Land disputes were stimulated when the common land/resource rights on village lands of the Maasai pastoralists became regulated and insecure. The analysis of past land disputes showed that space-place tensions on village lands can be presented as a platform on which spatial and property issues with complex power relations have been debated. The reduction of future land disputes will succeed only when/if local property rights to land and resources are acknowledged, especially in rural lands of the Tanzanian State.

We investigate the Einstein relation for the diffusivity-mobility ratio (DMR) for n-i-p-i and the microstructures of nonlinear optical compounds on the basis of a newly formulated electron dispersion law. The corresponding results for III-V, ternary and quaternary materials form a special case of our generalized analysis. The respective DMRs for II-VI, IV-VI and stressed materials have been studied. It has been found that taking CdGeAs2, Cd3As2, InAs, InSb, Hg1−xCdxTe, In1−xGaxAsyP1−y lattices matched to InP, CdS, PbTe, PbSnTe and Pb1−xSnxSe and stressed InSb as examples that the DMR increases with increasing electron concentration in various manners with different numerical magnitudes which reflect the different signatures of the n-i-p-i systems and the corresponding microstructures. We have suggested an experimental method of determining the DMR in this case and the present simplified analysis is in agreement with the suggested relationship. In addition, our results find three applications in the field of quantum effect devices.

Polymerization of methyl methacrylate in the presence of a mixed ligand complex, [N,N-ethylenebis(salicylideneiminato)](acetylacetonato)cobalt(III) in benzene was studied. The rate of polymerization was proportional to the square root of the concentration of the chelate and the monomer exponent was 1.67 and 1.69 at 60 and 70°C, respectively. The activation energy and the kinetic and transfer constants were evaluated. A free-radical mechanism has been proposed.

The notions of identity and teacher education have attracted considerable research over the years, revealing a strong correlation between teacher beliefs and practices and the resultant impact on pedagogical practices in the classroom. In an era where the use of digital technologies should be synonymous with teacher pedagogical practices and transforming education, there is a growing need for pre-service teachers to develop an identity that resonates with pedagogical practices that engage and connect with students in a positive and productive way. With many educational institutions also mandating that educators use digital technologies as a tool to support and enhance teaching, pre-service teacher education needs to ensure that students understand and develop a positive identity within this digital world. Current literature acknowledges that many educators adopt digital technologies in the classroom without sometimes fully understanding its scope or impact. It is within this context that this paper reports on a three-year study of first year pre-service education students and their understanding of identity in a digital world. More specifically, the study identifies how students currently use social and digital media in their personal and professional lives to identify themselves online in order to promote a positive image. The study also seeks to identify how these technologies and an understanding of identity can be utilised to promote a positive first year experience.
